Product Description

α-Select Gold Competent Cells are directly comparable to DH5α cells. They contain a lacZ marker that provides α-complementation of the ß-galactosidase gene for blue/white color screening and are ideal for construction of gene banks or for the generation of cDNA libraries using plasmid-derived vectors.

α-Select Gold Competent Cells also provide recA1 and endA1 markers to minimize recombination and enhance the quality of the plasmid DNA, allowing efficient transformation even with large plasmids.
